The pie chart is one of the most common graph
formats used for representing proportions or values of variables. Depending
on the selected type of graph (see the Quick tab), the pie chart will
display either raw values or counts (i.e., frequencies) of specific values
(such as those which can be displayed in Histograms).

Case
Weights. Click the Case
Weights button to display the Analysis/Graph Case Weights dialog box,
which is used to adjust the contribution of individual cases to the outcome
of the current analysis by "weighting" those cases in proportion
to the values of a selected variable.

Graphs
Gallery. Click the Graphs
Gallerybutton to display
the StatisticaGraphs
Gallery dialog box, which is used to easily switch among different
types of graphs.

Updating. Click
the Updating button to display
the following menu commands:

Auto. Select Auto
to disconnect the graph from the graph creation dialog box and connect
the graph directly to the spreadsheet. Any changes in the spreadsheet
data (including selection condition changes) will be immediately reflected
in the graph.

Manual. Select Manual
to disconnect the graph from the graph creation dialog box and connect
the graph directly to the spreadsheet. Any changes in the spreadsheet
data will be reflected in the graph only after a manual update is initiated.

Locked. Select Locked
to disconnect the graph from the graph creation dialog box and connect
the graph directly to the spreadsheet. The graph is linked to the spreadsheet,
but will not be updated when the spreadsheet data changes.

Analysis. Select Analysis
to connect the graph to the graph creation dialog box and disconnect the
graph from the spreadsheet. Changes to analysis options (such as fit type)
will be applied to all graphs created by the analysis.

Analysis/Updating. Select Analysis/Updating to connect the graph
to the graph creation dialog box and disconnect the graph from the spreadsheet.
The analysis (while open) will update the graph when the spreadsheet data
is changed. Once the analysis is closed, the graph will no longer update
when the spreadsheet data is changed.

None. Select None
to disconnect the graph from both the spreadsheet and graph creation dialog
box.
